弧底梯形渠的冻胀试验研究

An Experiment Study of the Frost-heaving of the Arc Base Trapezoidal Impervious Channel

混凝土衬砌弧底梯形渠道具有较好的抗冻胀性能,在我国北方大、中型防渗衬砌渠道中广泛应用,为了进一步探索衬砌厚度与冻胀变形的规律,在工程现场进行了不同工况的试验,总结了衬砌厚度与冻胀变形的规律,并应用价值工程理论对其技术经济指标进行了分析。

The arc base trapezoidal impervious channel with concrete lining is of better frozen-preventing performance, and ifs widely used in large and medium-sized channel which is of anti-seepage lining in North China. In order to explore the relationship between the lining thickness and frost deformation, we do experiments under different working conditions in the project field, summarize the law of lining thickness with frost deformation. This paper also utilizes the value engineering theory to analyze technical and economic indexes.
